COMPARATIVE EFFECTIVENESS AND SAFETY BETWEEN AMPHOTERICIN B LIPID-FORMULATIONS: A SYSTEMATIC REVIEW
Bibliographic record
Abstract
OBJECTIVES: It is not yet established the advantages between amphotericin B lipid complex (ABLC) and liposomal (L-AmB) in patients with invasive fungal infections refractory to usual doses of conventional AmB (d-AmB), previous renal impairment, or unacceptable d-AmB renal toxicity. This systematic review aims to compare ABLC and L-AmB effectiveness and safety outcomes in these subgroups of patients. METHODS: The search was performed on Medline, Cochrane Library, EMBASE, and LILACS databases. INCLUSION CRITERIA: treatment comparing L-AmB with ABLC; patients who had (i) refractory infection after being treated with d-AmB, (ii) previous renal impairment, or (iii) unacceptable d-AmB toxicity. Two investigators independently screened the search results, assessed trial quality, and extracted data. A total of 1,054 articles were identified in the literature. Among those, eleven were selected for full-text reading and five met the inclusion criteria. RESULTS: The five articles included reported on four separate observational studies. Overall, no significant difference was found in clinical relevant outcomes as new-onset dialysis, length of hospital stay, or mortality when comparing both lipid formulations. The studies reported a trend toward lower nephrotoxicity in patients treated with L-AmB. However, the results were imprecise and heterogeneous and the studies presented important methodological biases. CONCLUSIONS: The studies included in this systematic review pointed toward less nephrotoxicity events in the L-AmB group. However, due to low quality of evidence and no statistically significant differences in other clinical relevant outcomes, there is no definitive evidence of overall superiority in effectiveness or safety outcomes regarding one lipid formulation or another in this population subgroup.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
